A slope matched microstructure optical fiber for dispersion compensation over S + C+ L wavelength bands

This paper presents a microstructure optical fiber based on an octagonal structure for dispersion compensation in a wide range of wavelengths. It is shown theoretically that it is possible to obtain negative dispersion coefficient of - 821 ps/(nm.km) and relative dispersion slope (RDS) close to that of single mode fiber (SMF) of about 0.0036 nm

at 1550 nm wavelength. Besides the proposed octagonal microstructure optical fiber (O-MOF) offers high birefringence of 1.86×10

. Due to having superior optical properties, this proposed fiber with modest number of design parameters can be effectively used in broadband dispersion compensation and sensing applications.
